Question

我将导航抽屉图标更改为自定义图标时遇到问题。我目前不得不实现标准的抽屉图标，顶部有3条水平线，但现在我想用我的自定义抽屉图标替换它。

这就是我mDrawerToggle目前的情况：

mDrawerToggle=new ActionBarDrawerToggle(this,
    mDrawerLayout,
    R.drawable.app_icon,
    R.string.drawer_open) {
        // My code
    };

Answer 1

使用以下代码，它适用于V7 ActionBarDrawerToggle

mDrawerToggle.setDrawerIndicatorEnabled(false);

mDrawerToggle.setHomeAsUpIndicator(R.drawable.your_custom_icon);
 mDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
@Override
 public void onClick(View v) {
     if (mDrawerLayout.isDrawerVisible(GravityCompat.START)) {
          mDrawerLayout.closeDrawer(GravityCompat.START);
     } else {
         mDrawerLayout.openDrawer(GravityCompat.START);
    }
}
});

以下是取自的示例代码 Creating a Navigation Drawer

<强> Activity.class

public class MainActivity extends Activity {
    private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mDrawerToggle;
    ...

    public void onCreate(Bundle savedInstanceState) {
        ...

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                mDrawerLayout,         /* DrawerLayout object */
                R.drawable.ic_drawer,  /* nav drawer icon to replace 'Up' caret */
                R.string.drawer_open,  /* "open drawer" description */
                R.string.drawer_close  /* "close drawer" description */
                ) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                super.onDrawerClosed(view);
                getActionBar().setTitle(mTitle);
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                getActionBar().setTitle(mDrawerTitle);
            }
        };

        // Set the drawer toggle as the DrawerListener
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        mDrawerToggle.onConfigurationChanged(newConfig);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Pass the event to ActionBarDrawerToggle, if it returns
        // true, then it has handled the app icon touch event
        if (mDrawerToggle.onOptionsItemSelected(item)) {
          return true;
        }
        // Handle your other action bar items...

        return super.onOptionsItemSelected(item);
    }

    ...
}

Answer 3

您可以将此格式用于mDrawerToggle：

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
    R.drawable.CUSTOM_ICON, // Navigation menu toggle icon
    R.string.DRAWER_OPEN, // Navigation drawer open description
    R.string.DRAWER_CLOSE // Navigation drawer close description
    )

更改您的drawable，并确保它与代码中的名称相同。

这是主要的布局文件

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <!-- Framelayout to display Fragments -->

    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- Listview to display slider menu -->

    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/white"
        android:choiceMode="singleChoice"
        android:divider="@color/black"
        android:dividerHeight="1dp" />

</android.support.v4.widget.DrawerLayout>

这是主要的活动

DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.menuicon, // nav menu toggle icon
                R.string.app_name, // nav drawer open - description for
                                    // accessibility
                R.string.app_name // nav drawer close - description for
                                    // accessibility
        ) {
            public void onDrawerClosed(View view) {
                // getActionBar().setTitle(mTitle);
                // calling onPrepareOptionsMenu() to show action bar icons
                invalidateOptionsMenu();
            }

            public void onDrawerOpened(View drawerView) {
                // getActionBar().setTitle(mDrawerTitle);
                // calling onPrepareOptionsMenu() to hide action bar icons
                invalidateOptionsMenu();
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);

最后在 R.drawable.menuicon （你可以给你的图片ID）它会起作用。

Answer 5

这是主要活动

final DrawerLayout抽屉=（DrawerLayout）findViewById（R.id.drawer_layout）; ActionBarDrawerToggle切换=新的ActionBarDrawerToggle（抽屉，工具栏，R.string.navigation_drawer_open，R.string.navigation_drawer_close）；

function getProducts(array) {
    return array.map((_, i, a) => a.reduce((a, b, j) => a * (i === j || b), 1));
}

console.log(getProducts([1, 7, 0, 4]));
console.log(getProducts([1, 7, 3, 4]));

更改导航抽屉的图标
